What problem does it solve? Broken citation keys and fabricated or incorrect bibliography metadata cause Quarto and LaTeX renders to fail or silently produce wrong references. This Skill catches missing keys, likely typos, and unverifiable DOIs before a paper is rendered or released. ## Core Features & Use Cases - Citation Key Validation: Extracts citation keys from .tex, .qmd, .md, and .rmd sources and compares them against .bib entries, reporting likely typos at edit distance 1 and possible typos at distance 2. - DOI and Fabrication Checks: With --verify-doi, resolves DOIs through OpenAlex and searches Crossref for entries without DOIs, reporting a match matrix across title, first author, and year. - Safe Auto-Fix: --fix corrects only unambiguous citation key typos in source files and never rewrites bibliography metadata automatically. - Use Case: Before submitting a Quarto manuscript, run the validator on paper.qmd and references.bib with --verify-doi to confirm every cited key exists and every DOI resolves to the intended work. ## Quick Start Ask the AI to validate the citations in your Quarto or LaTeX document against your .bib file, optionally verifying DOIs and fixing unambiguous key typos.
